k40 relay
the dealership said i need a new supercharger bypass valve. i read on a partsgeek.com that this relay controls secondary air injection which is the supercharger valve right?
i got a p0060 code..which i think is a blown fuse or relay
thank you any help would be great
Part Number: W0133-1794938
Notes: This relay is used for various functions in different models such as Auxiliary Cooling Fan, Comort Control, Automatic Transmission, Secondary Air Injection, Terminal 15R, Terminal 15R2B, etc

I think you have the wrong part number.
What colour is the relay? Black, Grey or Yellow?
What size? Big or Small?
Some common relay found my CL203 coupe are:
Black big A002 542 13 19
Black small A002 542 11 19
A002-542-26-19 Grey big?
A002-542-14-19 Yellow big?
A002-542-12-19 Yellow small?

Secondary air injection is the pump that blows air into the exhaust under cold start conditions to improve emissions.

On the internet you can find instructions and demos on how to test a relay.
Best way to test your particular relay is to switch it out with another car that uses the exact same relay (ie: same Mercedes Part number: Black small A002 542 11 19). But this particular small black relay should be quite common in your car,... there should be about 5 of them in your front, side and back fuse box,.... so just switch them around and see if it fixes the issue you're experiencing.
Also search for a relay map so you have an idea of which relay you're switching.
